"India is our fastest growing large market. We are seeing our strongest demand here. There has been an acceleration in the large 18 months, especially as large enterprises want to be more collaborative and innovative," Sebastien Marotte, vice president Google Apps for Work at Google, told ET.

Though he declined to give India-specific numbers, he said that 2 million businesses worldwide were using Google’s enterprise products and about 4,500 companies were signing up every day. He added that about 1,000 companies, with over 10,000 employees, were using the software suite.

As it moves to get large clients, Google is increasingly taking on rivals such Microsoft’s Office 365 and IBM’s Lotus Notes. It even offers its products free to enterprises that are locked into another service provider’s contract.

"Sometimes companies are locked into enterprise agreements. So we offer it to them free for the remainder of their contract, so they don’t have to pay twice. We have about 2,00,000 companies evaluating Apps-for-Work while tied to another contract," Marotte said.

The company has also tied up with domain-name providers such as Big Rock to offer its applications to small-and-medium businesses when they begin the process of going online.
